John Buechler, a.k.a. PapaJohn, is the prominent specialist in the community of Movie Maker 2 users (the starter video editing software included in every version of Windows XP). He co-authored Movie Maker 2 - Zero to Hero, and wrote Movie Maker 2 - Do Amazing Things. Other writings include a tutorial in MaximumPC and weekly newsletters.
Movie Maker 2 is a basic starter application, and John encourages using other software that complements it. Virtual Dub was a core item in his toolkit since the beginning. His books and other writings routinely include it.

His http://www.papajohn.org website is an authoritative online reference for Movie Maker users. He moderates forums at http://www.SimplyDV.com and http://www.windowsmoviemakers.net, and is a regular at the microsoft.windowsxp.moviemaker newsgroup.
He won the annual Microsoft Most Valuable Professional (MVP) awards for three years straight: 2003 through 2005, and was further acknowledged by a special 2004 Windows 'Winny' award for outstanding community support by Microsoft.
